該紙機傳動系統(tǒng)采用由S7-226小型PLC作為系統(tǒng)的控制中心；由森蘭SB70G系列變頻器為驅(qū)動單元，頻率分辨率為0.01Hz以上；變頻專用電機作為執(zhí)行單元；歐姆龍PLC提供速度反饋信號，使紙機傳動在速度閉環(huán)運行，穩(wěn)速精度達(dá)可達(dá)0.01%。由PLC通過西門子MODUBUS協(xié)議、RS485網(wǎng)絡(luò)與變頻器實現(xiàn)速度鏈功能、速差控制、負(fù)荷分配功能、總車速升、降、各分部點的速度升、降及緊紙、松紙等功能，較理想地滿足紙機正常工作的需求。

3、速度鏈設(shè)計及速差控制
速度鏈結(jié)構(gòu)采用二叉樹數(shù)據(jù)結(jié)構(gòu)算法，完成數(shù)據(jù)傳遞功能。首先對各傳動點位置進行數(shù)學(xué)抽象，確定速度鏈中各傳動點編號，此編號應(yīng)與變頻器內(nèi)部地址一致。然后根據(jù)二叉樹數(shù)據(jù)結(jié)構(gòu)，然后根據(jù)二叉樹數(shù)據(jù)結(jié)構(gòu)，確定各結(jié)點的上下、左或右編號。即任一傳動點由3個數(shù)據(jù)確定其在速度鏈中的位置，填入位置寄存器數(shù)值該傳動點速度給變頻器后，訪問位置寄存器，確定子寄存器結(jié)點號，若不為0，則對該經(jīng)點進行相應(yīng)處理，直到該鏈完全處理完；再查兄弟寄存器結(jié)點號，處理另一支鏈。
